The reduction of peak areas at 2θ = 27.5 from melon to NCN-CN x was attributed to the reduction in the number of layers in NCN-CN x [47], [45]. The peak at 2θ = 13.1° disappeared in NCN-CN x because the strength of crystal decreased, which was related to the decrease in the size of melon during synthesis [32] .
Co-based oxides have been considered as one of the most promising materials for thermochemical energy storage (TCES) systems, however, the high operation temperature limits their applications. Specially, when Co 3 O 4-based materials are used in concentrated solar power (CSP) system, a large mirror field area is required to meet the …
Energy storage industry figures were among attendees at a celebration event on Tuesday at the White House, marking the passage of the Inflation Reduction Act. The event took place one month on from US President Joe Biden''s signing of the act. The legislation includes US$369 billion of measures to advance the country''s clean energy …

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of th…
